Treat registry as SSOT for Uploads

FileDownloadDispatchWorker looks only at the registry table
for things that have never been synced.

In order for the counts to be correct, we have to distinguish
between "never synced" and "failed" with "retry_count" being
"nil" for the former and "not nil" for the latter.

Feature flag is "geo_file_registry_ssot_sync".
